HABL3QUIN BUG ( Murgafttia histrionica Hahn) 
District of Columbia. 2. R. King (August 24): Four harlequin "bugs were found 
feeding on a spider plant in Potomac Heights. ..... 
Virginia. H. B. Derr (August 16): The harlequin bug is the most destructive 
insect we have this year. 
"•i . J. Schoene (August 22): During the past summer the harlequin bug has been 
reported from many sections of the State, causing serious injury to various 
cruciferous crops. This nest has been more numerous than for many years. 
H. G. tfalker and L. D. Anderson (August 26): The harlcouin bug is serious- 
ly injuring young kale and other cruciferous crops in Tidewater. Large num- 
bers of these bugs have been breeding in old seed kale fields, from which 
they are migrating to other fields. Several fields of young kale have been 
completely destroyed by migrating nynrohs and others have been more or less 
severely injured. In some places the nymohs have migrated from one- fourth 
to one-half of a mile, crossing a creosote barrier as if there were nothing 
there. In migrating from field to field the nymphs have caused some injury 
to corn. A large number of nymphs have become adults during the past week 
and those arc now flying rround and causing damage' over a much wider area. 
A small hymenopterous egg -o-rasite (which has been sent to Dr. Morrison for 
identification) is quite common in some fields. As' high as 30 -oer cent of 
the eggs collected in some fields have been found to /parasitized by this para- 
site.

in the southern part of the State, as several inquiries in regard to its 
control were received from there between August 15 and 22. 
Illinois. '7. p. Flint (August 19): There have been an unusually large num- 
ber of reports of this insect. These have come in from many points in the 
southern half of the State, the "farthest coming from Schuyler County, which 
is almost exactly half way up the State, about on the line with the city of 
Indianapolis. 
Missouri. L. Baseman (August 25): Still causing damage to cabbage and related 
crops at Columbia. Adults are laying eggs at present (August 26).

dant in Montgomery County and eastern Tennessee. 
Colorado. G. M. List (August 25): The harlequin bug spread farther north this
